Intel Woodcrest vs AMD Opteron vs Sun UltraSparc T1

It's high time for Intel to find a proper response, as the competition is taking the wind out of Intel's server CPU sails. What's the answer? A Xeon based on the Core architecture: Woodcrest. We compared the Core and K8 architectures just a month ago. Memory disambiguation, large OOO buffers and a large but low latency shared L2 cache should make the Core architecture more efficient in server related tasks than any other x86 CPU.
